ATTACHMENT TO FLOUR-PACKERS.

SPECIFICATION forming part of Letters Patent No. 251,392, dated December27, 1881. Application filed November 9, 1881. (No model.)

To all whom it may concern:

Be it known that I, JOHN PATRICK WARD, a subject of the Queen of GreatBritain and Ireland, and a resident of Minneapolis, in the county ofHennepin and State of Minnesota, have made certain new and usefulImprovements in Attachments to Flour-Packers, of which the following isa specification.

This invention relates to machines used in packing flour in barrels andother receptacles and it consists in a movable ring or plate encirclingthe lower end of the packer-tube, and adapted to rest upon the upperedge of the barrel to fill the space between the barrel and packer-tubeand rise and fall therewith, whereby the flour is prevented fromescaping while being packed, as hereinafter set forth.

The invention further consists in a cloth bag or hood connecting theabove-mentioned packin g-ring and the upper part of the outside of thepacker-tube, whereby the fine dust is prevented from escaping, ashereinafter set forth.

'I attain these objects by the use of the mechanism illustrated in theaccompanying drawings, in which- Figure 1 is a semi-sectional side view.Fig. 2 is a plan view on the line a? no of Fig. 1.

In the ordinary flour-packer, in which the empty barrel is raised upwardoutside the packer-tube and then caused to run downward as fast asfilled, a large amount of the flour is blown out by the motion of thescrew within the packer-tube and to avoid this waste is the object of myinvention, which consists in a ring, A, formed with its lower edge, a,fitting closely the outer face of the packer-tube B, but free to slideup and down thereon, while its upper edge, I), is a short distance awayfrom it, the outer face of the ring thus being at a slight angle to thetube B, so that it will fit all sizes of barrels into which it isadapted to fit, as hereinafter explained.

The upper edge of the ring A is provided with a fiat flange, (3,connected to the frame E of the packer by two or more chains, 0, whichregulate the distance downward of the rings A 0, but offer noobstruction to their upward movement around the tube B.

Secured to the flange O by ametal hoop or ring, (1, is a rubber ring, D,with its inner edge in contact with the outer surface of the tube B,thus forming a packing between them.

The flange 0 is adapted to rest upon the upper edge of the barrel F,while the ring A passes down into the barrel, as shown, when thelargest-sized barrels are used; but when a smaller size is used theinclined form of the ring A permits it to fit its interior upper edge.By this means, on any sized barrel that the tube B will enter, the ringsA (3 may be used, and form a packing between the tube and barrel andprevent flour being blown out at this point. The rings A O, by thisarrangement, will remain in contact with the barrel at all parts of itsmovement up and down, the chains 0 preventing them dropping oif from theend of the tube B when the barrel is removed.

If found necessary, rods G, attached to the outer edges of the flange Oand running up loosely through the frame E, and provided with coiledsprings 9, may be used to hold the rings A 0 down upon the barrel orforce them downward when the barrel is moving downward; but ordinarilythe weight of the rings themselves will be sufficient.

Some fine dust will work up between the rubber D and tube B, and toprevent this escaping to annoy the operator I attach a cloth casing orhood, H, around the tube B and flange O, to catch and retain all suchdust.

The rings A C may be made in two or more pieces attached to the loweredge of the tube B, and adapted to expand and contract against the innersurface of the barrel as the latter rises and falls;but the manner shownis preferable.

What I claim as new is-- 1. In a machine for packing flour in barrelsand other receptacles, a packing ring constructed substantially asdescribed and adapted to fill the space between the packing-tube andbarrel or other receptacle being filled, to prevent the escape of theflour at that point.

2. The combination of the tube B, ring A, flange O, and rubberpacking-ring D and the barrel or other receptacle, F, substantially asset forth.

3. The combination of the tube B, rings A C D, chains 0, and frame E,substantially as set forth.

4. The combination of the tube B, rings A O D, frame E, rods-G, springsg, and chains 5 a, substantially as set forth.

5. The combination of the tube B, ring A O, and cloth hood H,substantialiyas set forth.
